DEFAULT settings in OE6 won't lock in

[BURT]

I have

WINME
OE6

My DEFAULT settings
in OE 6 will not remain in DEFAULT SETTINGS in

Accounts--
Properties--
Advanced
Servers

Because of this problem--it keeps cutting me off from OE6 with ERROR messages and I must review and correct my settings. I click DEFAULT and APPLY after I correct my settings--but constantly it goes back to the improper settings. It also disables my MSGTAG program.

How can I get them to stay fixed?

Thanks
